I got a deep cut on my finger? im a 14 year old female.yesterday I got a deep cut on my finger. i got a tetanus shot about 3 to 4 years ago, the cut came from a dog food can. I got the cut under control and bandaged in about half an hour. Its been hurting for the whole day and it feels like there is somewhat some pressure around it, would it require another shot or medical help,im not sure how deep it is but part of the is skin is almost off so I could see inside of it? and a few mins. ago I got up from sitting down and had sudden pressure in my ears and I could barely hear anyting and my vision got blurry,I have been worrying a little so I am not sure if that was just from stress or should I be worried about it,I am fine now?
